IMPROVEMENT IN COMPOUND BUILDING-BLOCKS.

Speci'cation forming part of Letters Patent No. 123,385, dated February 6, 1872.

Specification describing a new and Improved Ornamental Building Material, invented by ANDREW DERROM, of Paterson, in the county of Passaic and State of New Jersey.

Figure l represents a perspective view of my improved ornamental buildin g-block. Figs. 2 and 3 are transverse sections of the same in molds.

Similar letters of reference indicate corresponding parts. f

The object of this invention is to produce a very inexpensive building material which will rank with the very best in the country, both as regards durability and appearance, but will be much less costly and more durable than material which is only valued for its appearance. My invention consists in forming brick buildin g-blocks with stone, met-al, or imitationstone faces, so that when put upon buildings they will constitute perfect and uniform blocks of greater strength and durability, and with the desired appearance on the face.

A in the drawing represents a buildingblock, composed of a number of bricks, which are cemented or. otherwise united together, and of stone, metal, or with imitation-stone face, a.. This latter, if applied as a plate by cement or by mechanical fastenings,is secured to the block of bricks, and the entire block can then be conveniently transported to suitable place, and put up as part of a building-front. Such blocks can be formed in boxes or molds B, as in Fig. 2, wherein they can be put up by By unskilled labor the blocks can be pre-4 pared and packed for transportation, and then pnt up with rapidity and precision. y

Having thus described my invention, I claim as new and desire t'o secure by Letters Patent- The compound building fblock herein described, as a new article of manufacture.
